Minus to "weight"

Food giving to consumers of current is made by means of a wire which is always connected in more or less difficult way to the battery in what it is possible to be convinced according to electroschemes of the following chapter.

The return chain is provided by electroconductive metal elements of a body or the engine. Thus a large number of expensive copper cable is saved. In most cases the short piece of a cable – namely where the consumer of electricity is located not directly on metal nevertheless is necessary for the return chain. For this purpose exists – distributed on all body – a certain quantity of so-called points of "weight".

The negative pole of the battery too, of course, is connected to a body, "weight" as auto electricians speak. So remember – "minus to weight".
